Gaoxiang Company has its own cold chain refrigeration research and technology development center and plans to build a national cold chain refrigeration technology development center with high-end test equipment and a complete research and development team and sound system in recent years.

Technical advantages of refrigeration unit supporting equipment products

With the German EBM company developing the motor energy saving project, the product than similar traditional motor energy saving more than 30%;

In the substitution research of refrigerants, CFCS that pollute the environment is replaced by HCFC-22 and HFC-134a, which have no CFC problem and no greenhouse effect.

Successfully used carbon dioxide as refrigerant two-unit production technology, equipment products ready to domestic high-end, international developed countries to supply users. The use of CO2 refrigerant replacement technology not only improves refrigeration efficiency, but also meets the requirements of environmental improvement, ADAPTS to the international trend of low carbon and environmental protection, and the emission reduction rate reaches 50% compared with the products using traditional refrigerants.

The elliptical tube heat exchanger technology is fully adopted. Compared with the circular tube, the elliptical tube has good aerodynamic characteristics, which can reduce the vortex area behind the tube and reduce the air resistance. Elliptical tubes enable a compact tube cluster structure. The application of elliptical tube heat exchanger air conditioning box air transmission power is about 50% of the corresponding circular tube, that is, the motor energy consumption is saved about 50%;

Using short tube heat transfer, vapor-liquid separation, automatic liquid discharge technology, reasonable arrangement of the number and position of tubes, increase product performance and efficiency, and reduce material consumption.

Humidifying fresh-keeping cooler technology

With the leap forward development of domestic cold chain logistics construction, the key equipment of cold chain logistics has been vigorously developed, and the shortcomings of traditional chillers with large energy consumption and poor effect are more obvious.

Fresh and moisturizing continuous chiller adopts a unique frequency conversion design and energy-saving and throttling device so that the cooling conditions remain uninterrupted, indoor temperature and humidity parameters change very little, cooling goods dry consumption is reduced, no external defrosting heat source power consumption, energy saving and emission reduction, greatly reducing operating costs.

Compared with the traditional chiller, the product also has a significant effect on the freshness and heat preservation of vegetables and fruits in cold storage, which significantly reduces the dry loss of vegetables and fruits in cold storage, and greatly reduces the rot rate of refrigerated goods.

The product has been identified by the expert group, and its overall technology has reached the level in China, and the material selection and process of fins have reached the international advanced level.

Frequency conversion energy-saving technology

Frequency conversion technology is to adjust the speed of the equipment by changing the input power frequency of the motor, so that the refrigerated container cooling capacity is consistent with the system load, and then the temperature in the box is stable within a certain range.

The frequency conversion control technology has remarkable energy-saving efficiency. When the air supply volume is 80% of the working air volume, the fan adopts frequency conversion adjustment, and its energy consumption is only 15% of the original, while the energy consumption is 93% by throttling adjustment, and the energy consumption is reduced by nearly half. When the air volume is reduced to 50%, the energy consumption of throttling regulation is 73%, and the energy consumption of frequency conversion regulation is only 15%. Therefore, the frequency conversion adjustment has a significant energy-saving effect.

Hot gas defrosting technology

Traditional air cooler defrosting usually uses process heat (hot gas) or electrical energy (electric defrosting) to melt, in this process, the cooling operation is interrupted and steam fog is formed, and the condensed water steam on the roof will form ice.

Compared with electric heating, the new defrosting technology not only shortens the time of hot gas defrosting by 40% but also reduces the heat load of the unit.
